Abstract
Improved electrophoretic media including a first particle of a first polarity and three particles of the opposite polarity, wherein the first particle and optionally one of the particles of the opposite polarity undergo a diminution of electrophoretic mobility with increased electric field. Such electrophoretic media enable full-color displays with very fast updates between white and black pixels.
